The Properties of Hydrophilic Aluminum Foil - KatrinLefr - 12-08-2020
The hydrophilic aluminum foil has strong hydrophiicity. It can be used in air conditioning to optimize the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%.In addition, the aluminum fin stock also has other advantages such as anti-corrosion, bacteria resistance and no odor. It is mainly used in high-end air conditioner, refrigerators, automobile air conditioners and automobile water tanks. Welcome to know its properties through the following table.Item of converter foilTechnical parameterFilm thickness1.0-20 µmHydrophilicity Initial hydrophilic angle ≤10°, continuous hydrophilic angle ≤20°AdhesionErichsen test(5 mm deep):no flaking, no delaminationCorrosion resistanceRN≥9.5(72 hours)Alkali resistanceThe coating is completely no bubble after being immersed in 20% NaOH at 20℃ for 3 minutesSolvent resistanceSample weight loss ≤1%Heat resistanceAt a temperature of 200℃ for 5 minutes, its performance and color are unchanged. At a temperature of 300℃ for 5 minutes, the coating film is a little yellowish.Oil resistanceThe coating is without bubble after a 24-hour immersion in volatile oil.Odor OdorlessWear on the moldThere is less wear on the mold.
